Flood Diversion Pipe Control for Ecological River Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flood protection systems require flood basins for water diversion and can unintentionally divert water during low water levels, leading to environmental harm and inefficiency.
Innovation Solution
A flood protection system with a main pipe and a branch element featuring an adjustable shut-off device that directs water through either a secondary pipe or back into the watercourse, controlled by a processor-controlled system with water level sensors and artificial intelligence, allowing automated diversion based on water levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water is diverted through pipes during normal conditions, then productivity is improved by preventing flooding, but object-affected harmful factors worsen as the riverbed dries out damaging flora and fauna
Solution Approach 1:
The system dynamically switches between two operational modes based on water level conditions: during floods, water is diverted through the pipe system to protect the flood-prone area; during normal conditions, the shut-off device opens to allow water to flow naturally through the riverbed, maintaining ecological balance. This dynamic adaptation resolves the contradiction between flood protection effectiveness and ecological preservation.
Solution Approach 2:
The system changes the flow parameter (water diversion vs. natural flow) based on water level parameters. When the water level exceeds a threshold indicating flood conditions, the system activates diversion; when water levels are normal, the system restores natural flow. This parameter-based control resolves the contradiction by adapting the system's behavior to actual environmental conditions.
2Reliability
If a rigid hollow construction is used for flood protection, then reliability is improved by preventing water overflow, but device complexity worsens due to permanent pipe installations
Solution Approach 1:
The pipe system serves multiple functions: during floods, it acts as a flood protection structure guiding water away from the flood-prone area; during normal conditions, it serves as a water conveyance structure allowing natural flow. This multi-functionality reduces the need for separate permanent flood wall structures, thereby reducing overall device complexity while maintaining reliability.
3Productivity
If drive turbine is installed in the pipe, then productivity is improved by increasing water flow velocity during floods, but use of energy worsens due to energy consumption of the turbine
Solution Approach 1:
The drive turbine converts the kinetic energy of flowing water during floods into rotational motion to increase water flow velocity through the pipe system. Instead of consuming external energy to pump water, the system uses the flood water's own energy to drive the turbine and accelerate flow. This converts the potentially harmful flood energy into a beneficial force that enhances flood protection effectiveness while minimizing additional energy consumption.

AI summary
A flood protection system (10) on a watercourse (16) with a flood-prone area (18) includes a main pipe (12) along the watercourse (16) in this flood-prone area (18). At least parts of the watercourse (16) are guided through the main pipe (12) in the direction of flow (28). A drive turbine (62) in the main pipe (12) increases the flow velocity of the flowing water (16) in the main pipe (12) in the event of flooding, the main pipe (12) flowing back into the flowing water (16).
